W3.CSS is Normalized

Normalizing a style sheet is done to:

  • Correct browser bugs
  • Remove browser inconsistencies
  • Assure common browser defaults
  • Normalize the styles of all HTML elements
  • Add CSS improvements

An extract from Normalize.css is used in W3.CSS.

This makes W3.CSS display HTML consistently in all browsers, and in line with modern web standards.
